Abstract: PROBLEM TO BE SOLVED: To reduce the GPS signal acquiring time of a wireless device.
SOLUTION: The wireless device is adapted to receive a reference signal, extract a snippet of the received reference signal, determine a time of reception for the snippet and transmit the snippet and time of reception to a position determination entity as part of a request for GPS aiding information. The position determination entity is adapted to continually receive and store a reference signal along with an associated time of reception, and receive the snippet and time-stamp transmitted from the wireless device. The position determination entity is further adapted to match the signal snippet to a portion of the stored reference signal, determine a time offset between the time-stamp and the time of reception of the matched portion of the stored reference signal, prepare aiding information for the wireless device, synchronize the aiding information to the wireless device using the time offset, and transmit the synchronized aiding information to the wireless device. The wireless device is further adapted to acquire the GPS signal with the aiding information including received timing information.

Abstract: PROBLEM TO BE SOLVED: To provide a method for determining a relative timing of a pilot signal transmitted from a base station with respect to a timing reference signal for base station and mobile station time calibration within a communication system that has position location capabilities.SOLUTION: A reference pilot signal having a known timing relationship to a timing reference signal is generated on the same carrier frequency on which a pilot signal is generated by a base station. The reference pilot signal is combined with the pilot signal generated by the base station and the time offset is determined between the reference pilot signal and the pilot signal generated by the base station.

Abstract: PROBLEM TO BE SOLVED: To achieve position determination in a wireless communication system with detection and compensation for repeaters. SOLUTION: In order to detect whether or not a remote terminal is under the coverage of a repeater in a wireless communication network, techniques may be based on (1) a list of base stations expected to be received under the coverage of the repeater and (2) a characterized environment of the repeater or (3) a propagation delay for a transmission received at the remote terminal. Additional ambiguity resulting from being under the coverage of the repeater may be also accounted for or compensated by (1) discarding time measurements from repeated base stations, (2) adjusting processing for position estimates, and (3) computing a series of position estimates based on multiple transmissions received from the same originating base station and selecting the best estimate, or (4) computing a series of position estimates based on multiple transmissions from multiple originating base stations and selecting the best estimate.

Abstract: Techniques to detect whether or not a remote terminal is under the coverage of a repeater within a wireless communication network, which may be based on (1) a list of base stations expected to be received while under the repeater's coverage, (2) the characterized environment of the repeater, and/or (3) the propagation delays for a transmission received at the remote terminal. Additional ambiguity resulting from being under a repeater's coverage may also be accounted for and/or compensated by (1) discarding time measurements from repeated base stations, (2) adjusting the processing for position estimation to account for the additional ambiguity due to the repeater, (3) computing a series of position estimates based on multiple transmissions received from the same originating base station and selecting the best estimate, and/or (4) computing a series of position estimates based on multiple transmissions from multiple originating base stations and selecting the best estimate.
